cycloaddition of arylazides with 1,2-dihydro-isoquino line derivatives leads to new triazolinic adducts. The thermolysis of these latters followed to a hydrolysis conducts to 1,4-dihydroisoquinolin-3(2)-oes. The structure of the adducts and other products are assigned. The regio and diastereospecificity of the cycloaddition reaction are discussed on the basis of 1H NMR data.
芳基叠氮化物与1,2-二氢-异喹啉系列衍生物的1,3-偶极环加成反应会生成新的三唑啉加合物。这些后者的热解随后水解为1,4-二氢异喹啉-3(2 )-oes。确定了加合物和其他产品的结构。基于1 H NMR数据讨论了环加成反应的区域和非对映特异性。
Dipolar 1,3-cycloaddition of arylnitriloxides on 1,2-dihydroisoquinolines in a two-phase medium
The 1,3-dipolar cycloaddition of arylnitriloxides on 1,2-dihydroisoquinoline derivatives led to new 3-aryl, 3a-8,9,9a-tetrahydro[5,4-c]-isoxazoloisoquinoline adducts. The regioselectivity of the cycloaddition reactions is discussed on the basis of 1H and 13C NMR data.
